TIDA-00851

Design files

Overview

The TIDA-00851 reference design is a single-chip solution for a 2-wire, 4-20mA loop-powered system including a 4-wire RTD analog front-end. The built-in processor enables the usage of compensation algorithms, increasing the system performance. The design is ideally suited for space constraints applications and operates at high ambient temperatures with low power performance.

Features
  • 4-wire RTD Sensors (PT100)
  • Loop-power 4-20mA current interface
  • Ambient Temperature: -40ºC to +150ºC
  • Designed to meet: IEC 61000-4-2, IEC 61000-4-4 and IEC 61000-4-5 specifications
